I’ve been playing around with the iPadOS 18 calculator, and some of the stuff is neat, but I think it’s probably more of a threat to Soulver and the like, than it is to PCalc.
It doesn’t do RPN, custom layouts, user functions / conversions / constants, multiple memories, hex/oct/binary, visual themes, and a lot more that PCalc does. It does have nicer expression based entry, which is something I want to add.
The Math Notes stuff feels like it’s a separate app.
Also, no bananas whatsoever!
